HD74AC273

Octal D Flip-Flop

Description

The HD74AC273 has eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The

common buffered Clock (CP) and Master Reset (MR) inputs load and reset (clear) all flip-flops

simultaneously.

The register is fully edge-triggered. The state of each D input, one setup time before the Low-to-High

clock transition, is transferred to the corresponding flip-flops’s Q output

All outputs will be forced Low independently of Clock or Data inputs by a Low voltage level on the MR

input. The device is useful for applications where the true output only is required and the Clock and Master

Reset are common to all storage elements.
